#
# This is the makefile for ne.
#
# The default build relies on terminfo, but you can specify NE_TERMCAP=1 to
# rely on termcap, or even NE_ANSI=1 to rely on termcap and to use by default
# the built-in ANSI terminal description. For example:
#
#     make
#     make NE_ANSI=1
#     make NE_TERMCAP=1
#
# If you use NE_ANSI=1 or NE_TERMCAP=1, no external library is needed.
#
# Specifying NE_DEBUG=1 will enable debugging info and will compile in a
# number of assertions. Moreover, specifying NE_NOWCHAR=1 will remove the
# calls to wide character versions of toupper(), tolower(), isspace(), etc.,
# and also calls to wcwidth().
#
# Defining ALTPAGING will create an ne with slightly different configuration:
# - PageUp and ^p map to PageUp (rather than PrevPage)
# - PageDown and ^n map to PageDown (rather than NextPage)
# - Home and End map to MoveSOL and MoveEOL (rather than MoveIncUp and MoveIncDown)
# - Key 1FF ("Esc Del", "[Del", or "Alt-Del")  maps to AutoIndent
# - (Shift-,Ctrl-)(F5,F6) shift left and right by (tabs,spaces)
# - RequestOrder is set, so requesters display in column major order.
# Some users may prefer this to the historical settings.
# N.B.: This will cause ne's operation to differ slightly from the documentation.
#
#     make OPTS=-DALTPAGING
#
# By changing the value of NE_GLOBAL_DIR, you can change the directory
# where ne tries to read system-wide information (configuration
# files, etc.).
